A conventional mounting device of this type will be explained with reference to FIGS. 3 and 4. In the figure, 1 is a bus bar for the neutral line, and a main terminal 2 to which a power line (not shown) is connected and a number of branch terminals 3 to which neutral lines (not shown) are connected are arranged. . Reference numeral 4 denotes an insulating stand that supports the bus bar 1, and is composed of a support part 4a that supports the bus bar 1 by caulking it with studs 5, and a fixing part 4b that fixes the support part 4a to the base 7 at a position away from the bus bar 1. . 4A is the surface facing the base 7 of the fixed part 4b of the insulating stand 4, and 6 is the fixed part 4b of the insulating stand 4.
8 is an insulating plate laid on the base 7.

て設けられる。ブスバー１は絶縁台４の支持部４
ａで支持されてベース７との絶縁距離を保つてい
る。 Since the branch terminal 3, which is a live part, is located close to the insulating stand 4, the insulating plate 8 for preventing ground faults is provided beyond the insulating stand 4. The bus bar 1 is a support part 4 of an insulating stand 4
a to maintain an insulating distance from the base 7.

があつた。
In the conventional mounting device as described above, the insulating base 4 is a molded product of synthetic resin, so it is hygroscopic but does not shrink, so there is no problem, but the insulating plate 8 is generally a fiber board, so it is not hygroscopic. Since the insulating plate 8 under the surface 4A of the insulating stand 4 becomes damp, it will contract in the thickness direction due to the applying force of the mounting screw 6, and the gap between the insulating board 4 and the surface 4A of the insulating stand 4 will shrink in the direction of the pressurizing force. There was a problem that a gap was created and the insulating stand 4 wobbled.
この考案は、かかる問題点を解決するためにな
されたもので、絶縁板８の厚み方向の収縮による
絶縁台４の取付けガタを防止することのできる分
電盤の中性線用端子台の取付装置を得ることを目
的とする。 This idea was made in order to solve this problem, and it is possible to install a terminal block for the neutral wire of a distribution board that can prevent the mounting looseness of the insulating stand 4 due to shrinkage of the insulating plate 8 in the thickness direction. The purpose is to obtain equipment.
この考案に係る取付装置は、絶縁台の固定部の
ベースに対向した面に座部を突設し、かつ絶縁板
にこの座部を嵌める孔を穿設したものである。
The mounting device according to this invention has a seat protruding from the surface facing the base of the fixed part of the insulating stand, and a hole in which the seat is fitted is bored in the insulating plate.
この考案においては、絶縁板の孔に座部を嵌め
て絶縁台を取付ねじによりベースに直に取付ける
ようにしたから、絶縁板が厚み方向に収縮しても
絶縁台がガタつくことがない。
In this invention, the seat is fitted into the hole in the insulating plate and the insulating stand is directly attached to the base with the mounting screw, so even if the insulating plate shrinks in the thickness direction, the insulating stand does not wobble.
第１図、第２図はこの考案の一実施例を示す図
であり、１，４〜８は上記従来装置と同一のもの
である。９は絶縁台４の固定部４ｂの面４Ａに突
設した座部、１０は絶縁板８に穿設した座部９を
嵌める孔である。
FIGS. 1 and 2 are diagrams showing an embodiment of this invention, and numerals 1, 4 to 8 are the same as the conventional device described above. Reference numeral 9 designates a seat projecting from the surface 4A of the fixing portion 4b of the insulating stand 4, and reference numeral 10 designates a hole drilled in the insulating plate 8 into which the seat 9 is fitted.
このように座部９によつて絶縁台４をベース７
に直に取付けられるので、絶縁板８が湿気を帯び
て厚み方向に収縮しても面４Ａとの間にすき間が
できるだけで絶縁台４がガタつくことがない。ま
たこの座部９は固定部４ｂの面４Ａにのみ設けて
あるので絶縁効果の低下はない。 In this way, the seat 9 connects the insulating stand 4 to the base 7.
Since it is directly attached to the insulating board 8, even if the insulating board 8 becomes damp and contracts in the thickness direction, a gap is created between the insulating board 8 and the surface 4A, and the insulating stand 4 does not wobble. Further, since this seat portion 9 is provided only on the surface 4A of the fixed portion 4b, there is no reduction in the insulation effect.
上記実施例では座部９の幅が絶縁台４の幅と同
じものを示したが、座部９の幅を絶縁台４の幅よ
り小さくすると、座部９と絶縁板８の孔１０との
すき間が絶縁台４の側方に露出しないのでさらに
高い絶縁効果が得られる。 In the above embodiment, the width of the seat part 9 is the same as the width of the insulating base 4, but if the width of the seat part 9 is made smaller than the width of the insulating base 4, the width of the seat part 9 and the hole 10 of the insulating plate 8 are Since no gaps are exposed on the sides of the insulating stand 4, even higher insulation effects can be obtained.
また上記実施例では角形の座部９を示したが、
円形であつてもよいし、円形であると絶縁台４の
面４Ａへの座部の加工がしやすいし、絶縁板８の
孔１０の加工もしやすくなる。 Furthermore, although the square seat portion 9 was shown in the above embodiment,
It may be circular, and if it is circular, it will be easier to process the seat on the surface 4A of the insulating stand 4, and it will also be easier to process the holes 10 in the insulating plate 8.
この考案は以上説明したとおり、絶縁台の固定
部のベースに対向した面に座部を突設するという
簡単な構造により、絶縁台をベースに直に取付け
できるので絶縁板の厚み方向の収縮による絶縁台

As explained above, this idea has a simple structure in which the seat protrudes from the surface of the fixed part of the insulating stand opposite to the base, which allows the insulating stand to be directly attached to the base, thereby reducing the shrinkage in the thickness direction of the insulating board. This has the effect of preventing the installation of the insulating stand from wobbling.
